Flourish Potassium™ is a highly concentrated potassium supplement designed to meet the specific nutrient needs of aquatic plants in a planted aquarium. Potassium, an essential macronutrient, plays a critical role in plant growth, influencing processes such as photosynthesis, nutrient transport, and overall cell function. In rapidly growing systems or aquariums with low mineral content in the source water, potassium can become depleted, limiting plant growth and leading to signs such as yellowing in older leaves. Flourish Potassium™ provides a concentrated 50,000 mg/L solution of potassium, effectively preventing depletion and ensuring sustained, vigorous plant growth in your aquarium.

A key advantage of Flourish Potassium™ is its use of potassium sulfate as the source of potassium. Unlike other potassium supplements derived from potassium nitrate or potassium phosphate, which can also add nitrogen or phosphorus to the system, Flourish Potassium™ allows hobbyists to target potassium levels independently without affecting the nitrogen or phosphorus balance in the aquarium. This makes it an ideal choice for aquarists who wish to adjust potassium levels precisely, without disrupting the NPK (nitrogen, phosphorus, potassium) ratio. By maintaining optimal potassium levels, Flourish Potassium™ helps ensure that plants receive the necessary nutrients to thrive, promoting healthy, lush growth while preventing nutrient deficiencies.
